Intel Arc G3 Extreme vs Intel Arc Pro B390 Comparison

Head-to-Head Benchmarks

The recorded data contains no benchmark scores for either the Intel Arc G3 Extreme or the Intel Arc Pro B390. Both entries show an average benchmark score of 0, and the head-to-head benchmark comparison list is empty. Neither part has any nearest rivals listed, so no relative performance deltas can be derived from the database. The absence of measured results means the two products cannot be ranked by compute throughput, gaming frame rates, or professional application performance based on the current dataset. Both GPUs occupy the 50th percentile among all GPUs in the database, which is a neutral position reflecting the lack of recorded measurements rather than a verified performance tier.

Architecture Differences

The Intel Arc G3 Extreme and the Intel Arc Pro B390 share the same underlying silicon in nearly every respect. Both use the Panther Lake chip and the Xe3-LPG architecture, fabricated on a 3 nm process at Intel. The transistor count and die size are listed as unknown for both, so no die-level comparison is possible. The core configurations are identical: 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. Neither part reports tensor core counts. The compute throughput matches exactly at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16, with the FP16 figure expressed as a 2:1 ratio. Pixel rate is 60.00 GPixel/s and texture rate is 120.0 GTexel/s for both.

The only architectural distinction in the database is the generation label. The Arc G3 Extreme belongs to the Arc Graphics-M (Panther Lake) generation, while the Arc Pro B390 belongs to the Arc Graphics-WM (Panther Lake) generation. The M designation suggests a mobile-oriented positioning, while WM indicates a workstation-oriented mobile part, but the hardware specifications recorded for both are indistinguishable. Clock behavior is identical: a 300 MHz base clock and a 2500 MHz boost clock. There is no game clock listed for either. Memory handling is also identical, with both using system shared memory, a system shared bus width, and system dependent bandwidth. The API support matches completely, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are listed as integrated graphics processors with an IGP slot width and IGP bus interface, drawing no external power connectors.

Where Each One Wins

Because the database contains no benchmark results for either GPU, the wins column shows zero for both parts. The Arc G3 Extreme has no recorded victories, and the Arc Pro B390 has no recorded victories. Neither product can be declared superior in gaming, rendering, compute, or any other workload category based on measured data.

The Arc Pro B390 does have one distinction in the database: it lists a predecessor, the HD Graphics-WM. The Arc G3 Extreme lists no predecessor. This indicates the Pro B390 is positioned as a replacement within the workstation graphics line, while the G3 Extreme appears to be a new entry without a direct prior model in the database. The production status for both is Active, meaning neither is discontinued or end-of-life.

The Arc G3 Extreme carries a later release date of May 31, 2026, while the Arc Pro B390 was released earlier on January 26, 2026. This roughly four-month gap in release timing is the only temporal difference between the two parts. It does not translate into any performance advantage in the recorded data, as neither has benchmark scores to compare.

Specification Differences

The specification sheets for the two GPUs are identical across every measurable field except for generation, predecessor, and release date. The Arc G3 Extreme uses the generation label Arc Graphics-M (Panther Lake), has no predecessor listed, and was released on May 31, 2026. The Arc Pro B390 uses the generation label Arc Graphics-WM (Panther Lake), lists HD Graphics-WM as its predecessor, and was released on January 26, 2026.

All other fields match exactly. Both run on the Panther Lake chip with Xe3-LPG architecture on a 3 nm Intel process. Both have a 300 MHz base clock and a 2500 MHz boost clock. Both use system shared memory with system dependent bandwidth. Both have 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Both deliver 60.00 GPixel/s pixel rate, 120.0 GTexel/s texture rate, 7.680 TFLOPS FP32, and 15.36 TFLOPS FP16. Both draw 80 W TDP, use an IGP slot width, have no power connectors, and use an IGP bus interface. Both have portable device dependent display outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has a launch MSRP listed.

FAQ

Q: Are the Intel Arc G3 Extreme and Intel Arc Pro B390 the same GPU?

A: In terms of recorded hardware specifications, yes. Both use the Panther Lake chip, Xe3-LPG architecture, 1536 shading units, 48 TMUs, 24 ROPs, 12 ray tracing cores, 7.680 TFLOPS FP32, 80 W TDP, and identical clock speeds. The only differences are the generation label, the predecessor entry, and the release date.

Q: Which GPU has a higher boost clock?

A: Neither. Both the Arc G3 Extreme and the Arc Pro B390 have a boost clock of 2500 MHz and a base clock of 300 MHz.

Q: Do these GPUs have dedicated video memory?

A: No. Both use system shared memory with a system dependent bandwidth. The memory size, type, and bus width are all listed as system shared or system dependent.

Q: What is the difference in release timing?

A: The Arc Pro B390 was released on January 26, 2026, and the Arc G3 Extreme was released on May 31, 2026. The G3 Extreme launched later by roughly four months.

Q: Does either GPU support ray tracing?

A: Both GPUs include 12 ray tracing cores. They also both support DirectX 12 Ultimate (12_2), which includes ray tracing features.

Q: Which GPU has a predecessor in the database?

A: The Arc Pro B390 lists HD Graphics-WM as its predecessor. The Arc G3 Extreme has no predecessor listed.

Q: What is the power draw of each GPU?

A: Both are rated at 80 W TDP. Neither requires external power connectors, and both use an IGP slot width.

The Verdict

The database currently provides no measured performance data for either the Intel Arc G3 Extreme or the Intel Arc Pro B390. Both parts show an average benchmark score of 0, an empty benchmark list, and no nearest rivals. The wins count is zero for each. Any decision between the two must therefore rest on the non-performance fields that do differ.

The Arc Pro B390 has the earlier release date of January 26, 2026, and a documented predecessor in HD Graphics-WM. That places it in a workstation-oriented lineage, and its generation label Arc Graphics-WM (Panther Lake) reinforces the workstation positioning. The Arc G3 Extreme, released May 31, 2026, carries the generation label Arc Graphics-M (Panther Lake), which points to a mobile-oriented positioning. The M versus WM distinction is the only substantive difference in the record.

For a user prioritizing the workstation lineage, the Arc Pro B390 is the choice supported by the database, as it has a predecessor and a generation label tied to the WM series. For a user prioritizing the mobile-oriented label, the Arc G3 Extreme is the choice. Since the compute specifications are identical, including 7.680 TFLOPS FP32, 15.36 TFLOPS FP16, 12 ray tracing cores, and an 80 W TDP, the decision cannot be made on raw capability. The data supports a verdict based on positioning and release timing: the Arc Pro B390 is the earlier workstation-oriented part, and the Arc G3 Extreme is the later mobile-oriented part. Neither can be recommended on benchmark evidence because none exists in the database.
